between the DS1 CONV board and the Fiber Endpoint. See MO SYNC for
diagnosing slip problems.
System Technician-Demanded Tests: Descriptions
And Error Codes
Always investigate tests in the order presented in the table below. By clearing
error codes associated with the
Failure Audit
for example, you may also clear
errors generated from other tests in the testing sequence. Tests 788 and 789 are
executed by the TN574 DS1 Converter circuit pack only.
NOTE:
Test #984 is not an actual demand maintenance test. This test number is
used to report results of the
clear firmware-counters
command. Refer to
the table for Test #949 to interpret ABORT codes for Test #984.
Reset Test (#787)
This test is destructive.
DS1 CONV circuit pack is reset via the reset board command. When the circuit
pack is reset, firmware executes a series of diagnostic tests on the circuit pack.
The results of these tests are queried from the board when the board is inserted
after completion of the reset sequence. If any one of the diagnostic test fails, the
error log will have an entry of error type 1 for this circuit pack location, and the
alarm log will have an entry of ON-BOARD MAJOR alarm.
The reset sequence will take about one minute to complete.
